TDI 75 remap longevity

You’re never going to prove or disprove VW motorsport’s assertion
Indeed. It’s also impossible to disentangle the remap from the driver and other associated variables. If, statistically, more remapped cars (throughout wider society, not within this community) die at a younger age, can the blame be at all attributed to the remap itself? Perhaps those who remap their cars are statistically more likely to drive their vehicles in a punishing, unsympathetic manner. Perhaps those drivers would have killed their vehicles prematurely anyway, even had the car not been remapped. Controlled scientific studies would be challenging to conduct.

So for the way a lot of people use their A2’s it’s probably fine, though that’s a million miles away from saying that any manufacturer could safely increase their engine’s output by x% with no adverse effects.
The manufacturers have to take many variables into consideration when writing the original map. I discussed throttling the output for insurance purposes in my previous post in this thread. Another factor is that fuel quality varies throughout the world. My remapped A2 is always fed the high quality fuel that we’re all used to in Western Europe. The remapping process was done using good fuel, and assumes that good fuel will continue to be used. However, had the same car been bought by someone who exported it to a less affluent area of the globe, they’d have needed a map that was happy running on poor quality ‘jungle juice’.
Car manufacturers need to write a map that’ll cope with huge variations in conditions and still run reliably.
If I was to drive my A2 overland to South Africa, via the Middle East and through Sudan, etc, it may be prudent to drive on a standard factory map and accept less oomph. Anyone up for a road trip!?

Cheers,

That's a journey and a half! Take a spare fuel button and earth cable 😆

If you map a car sensibly but drive steady I doubt you'll do much damage, but some oomph if you need it. The power doesn't get used unless you put your boot down.
 
Mine now near 250k miles, still going strong though unfortunately it didn't quite make the 250k mark without needing the original battery replacing...!
